Help Identify Part on Top of Radiator

[Safari Wagon]

I've got a small leak from this part which I believe is associated with power steering. Can someone please help me identify this part? This is on a 3VZ but may be the same across the Camry lines. Any suggestions on fixing it? (Its not leaking from the hose or connections)


Thank you!

In before OMG DEVIL HYDRAULIC FAN ISSUES. I seriously want to fins out how to swap the 3VZ's fan to an electric unit.

Pretty sure that's a filter for the fluid returning from the hydraulic fan motor. Therefore I'm pretty sure only the 3VZ-equipped Camrys have it.

easy kinda ...... um close loop the lines build a custom shroud like this



ac line will connect the left fan like normal but put a pig tail on it with a diode so when the fans turn on for heat issue wount send a current back

then wire the second fan to either a universal control

or to a solenoid that opens the fluid for the fan will turn on a relay for that fan

i can't give a defiant answer to any of this since the 3vz manual doesn't open on my computer, but in theory this will work on any car (for me it was the 7m and 22r) since your not relying on any in car component to control the fans (controller method it has a pickup for the clutch on the ac so it will turn the fan on) but if my method to pick up signal from a solenoid is right that will save the cost of the controller.

now the question is will any ps parts from the mz bolt on and delete the hydrological lines

94 mz half had hydrological fans

Hey thanks chronoti! I didn't know that.

I am not really following....
So it is a hydraulic fan line / filter.
Does it use the power steering fluid?
Can I just replace the filter and hope the leak goes away?
Will I have to bleed the PS system after?

I don't really want to rewire anything. The leak is minor and everything works fine. I may just leave it alone if its a lot of trouble.

[BMR]

Yep, it's filtering powering steering fluid; which is actually ATF. The power steering pump on 3VZ-FE equipped Camrys (and some early 1MZ's I just learned) is actually two pumps, pancaked together into one physical unit. One runs the power steering, the other the hydraulic motor-powered fans. They share the same fluid reservoir.

So if it's leaking, you could replace it. It'll self-purge any air that gets introduced. It should be pretty simple to do.

think I got it :P assuming all the 3vzs' were all the same and for a wagon
Assuming this is it( circled in red)

pnc 16091

16091 FILTER SUB-ASSY, HYDRAULIC MOTER OIL
16091-20010 1MZFE, 3VZFE..MCV10, VCV10..NAP
16091-62020 3VZFE..VCV10..NAP



Hope that helps (if it hooks up to something else going towards the driver side its definatly it) as u can see in the pic it goes to a motor)

i was just able to open the 3vz fsm so i'll update the swap to electric

fsm doesn't include that if it controls fan speed by pulse width (unable to use it to control fans) or simple on off (can use it to use fans) so neh ken

[Safari Wagon]

Thank you all! That certainly does help!
I know I can always rely on my fellow TN'ers.

[adalex]

if u look at the pic chronoti posted the part ur referring to is listed as Oil Filter

[BMR]

Good grief!!!.... checked online a few places and that filter is over $100!!

[chronoti]

yes, but if you look at the diagram that alex posted it is connected just by 2 ring clamps so you can go down to napa and get a good quality wix universal ps filter and install it

also on alex picture you see that it lists the other part number for the 94 mz

That's what I thought!

That was the second thought that crossed my mind

If I can find one that is the same diameter, I can probably re-use the bracket too.

This also got me thinking of how a filter can be leaking.... I have a small drip right at the bottom of the bracket. I don't feel any oil around the in / out points but I probably have to look at that a little closer. I just have a hard time imagining a filter leaking somewhere other than the connection points
